Highlights include a ransomware-linked data leak tied to India's Kudankulam nuclear plant via a contractor, a ransomware attack halting Coca-Cola's fairlife U.S. production, and ShinyHunters' ongoing Salesforce-focused extortion campaign hitting Fluke Corporation and Ingram Content Group. Other incidents include a healthcare breach at Australian clinic network Partnered Health, a law firm SSN exposure at WilmerHale, a Lidl customer data leak across Europe, and a dormant browsing-history collector found in the widely-installed ModHeader browser extension.
